Leiters Patent N 97,065, dated November 23, 1869.

IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the sama To all whom.' it 'may concern:

Be it kno'wn that we, ALBERT A. EASTON, of Kil lingly, and AnNoLD J. HAnuIXG'roN, ot' Plainfield, county ot' Windham, and State of Connecticut, have invented certain llew alld useful Illlprovcllleuts ill the Manufacture of lWater-Ylfileels; alld to ellable others skilled ill the art to lllake alul use the same, `we will proceed to describe its construction, referring to the drawings, in wllich the salue letters` indicate like parts in each of the figures. l

The llature of tllis invention will be fully understood from the specitieaton alld drawings.

The object desired to be attained thereby is to simplifyY and clleapell the construction, and thereby render `itluol'e eicient and durable for use.

I n the accompanyingl drawings- Figure 1 is a perpelldiclllar side view. Figure 2 is a top or plan view. Figure 3 is all edge view of the wheel.

A is the top plate. of the wheel, through which the 'shaft D passes, and to which the wheel is tirmly secured, by means ot' keys or nuts.

The lower elld of said shaft is tted to and works in or on a step, a, formed ill or on the bridge C, and is secured to the wlleel-box, mulerneath alld near the centre of the wheel.

B is the bottoni plate or rim of the wheel, the outside dialneter of which is the salue as that ofthe plate A. Tile inside diameter or opening is about tive-sevenths otl its whole diameter, or the width of this plate or rim li is about olle-seventh of the whole diameter of the plate or riln li. The distance betwl en Athe plates A B is ascertained bythe desired capacity or depth of bucket required.

To show the shape alld construction of'thc several buckets, we will single out one and describe it, showing at. the same time its relative position with the lille fr, and the several buckets which lllakc up the wheel.

E is a perpendicular plate., thrilling one side of the bucket, and tills the space between the top plate A alld rim ll, and ill thc lille x from the poillt l on the outer edge of the plate or rilll, to the point 2 011 the inner edge of the saine, plate l5.

l5 is aperpendil'ular, angular, inward-projecting portion of the bucket or plate E, arranged inits relative position, (sec lille a: a 1,) and connected with said plate, as sllowll at 2.

The. relative position and angle of the plates E and E' with each other, and the several buckets of the wheel, will be seen by the. lines :c x, x :l: x.

F is a sloping or dowaward-inclined bottom from t-lle lower edge of the plate E. Y

. t G is a perpendicular plate, extendingr down from the inside edge of the rim-plate B, alld intersects with the lower or outer edge of the bottom plate F, which forms the entire bucket. A

All the other buckets are forulc'd iu the same way. H is a spiral water-conducting box, inside of which 'the wheel is arranged, the upper and lower plates ot' which are the same distance apart astthe upper and lower pla-tes A B of the wheel, the outer. edges ot' which, or the space between the outer edges, is closed up by a partition or wall, I.

J is a gateway, through which thc water is allowed to tlow into said box, and nearly or quite surround the wheel.

Thus the pressure of the water is brought to bear on all or nearly all the buckets at the same time, and is allowed. afree and unobstructed discharge or exit from the wheel.

K is a dome or bridge, which arches the wheelopening of the box H, and forms a support for the upper end ofthe shaft D. This wheel being of equal deptll with the box H, the lower eld of its shaft D is set ill or ou the step a, a-nd the upper end ill the box or bearing L, so as to bring the upper and lower surfaces ofthe wheel alld water-box flush with each other and allow the water to expend its force and power upon the wheel,'and a free unobstructelil cxittherefrom.

In the construction or manufacture of these wheels, we propose to cast the wheel ill one piece of metal.. We also propose to cast the spiral case or box in one piece of lnetal, by means of patternsl alld nloulds, con-v structed or formed ill the common way otmaking patterns and lnoulds for producing castings.

By this iu'lprovement, we are enabled to greatly cheapen the manufacture ot' water-wheels, and pro duce a lnore perfect and economical wheel.

XVe believe we have thus showll the nature, c0ustruction, and advantage of this invention, so as to enable others skilled in the a-rt to make and use the salue therefrom.

What we claim, therefore, and desire Vto secure by Letters Patent, is-,

The arrangement of the plates .E, E', G, and F, with the plates A ill combination with the spiral water-box H, substantially as set forth.
